Some very good points. Arable farming is not at all ‘natural’ but I’m certain that 7billion people can’t survive without it. However I do believe improvements can be made but I believe that this can be best done by the actual farmers themselves, not by crude blanket bans. There should be carrots to encourage it and big sticks for those disobeying best practices. Just my opinion fwiw.I don't know how not using any agchem is magically great for the environment? Errrr you are growing a crop in monoculture and annually removing it for your own gain. Whether you plough it, pre-em it, whack it with dursban, temik or aphicide or even set the standing crop on fire is absolutely irrelevant- it is land in production and a million miles away from any natural habitat I know of.
Playing the I don't want to kill everything card is a bit rich given that production agriculture has been doing that since the hand hoe was invented.
If agriculture wants to be as green as possible it should adopt two approaches- produce the maximum economic yield from an area of land OR allow land to return to a completely wilderness state untouched by the hand of man as far as possible, which will eventually become climax forest and support the maximum number of species.
Claiming aphicides are terrible for the environment is like complaining about speeding during an F1 race.
Predators in an arable field, how exactly do these survive passes by combines, cultivators, drills and ring rollers? Ive chanced my arm with BYDV and got away with it before but you din't see me saying aphicides are terrible and no one should use them.
